![]() A recent 2015 systematic review published in Manual Therapy further supports the use of RC strengthening and stretching as an effective treatment for subacromial impingement. Even if you aren’t experiencing any symptoms, RC strengthening should definitely be incorporated into your workout regime. Subscapularis: This muscle is situated on the front side of your shoulder, and performs internal rotation of the shoulder jointĪ strong and competent rotator cuff provides the stability that the shoulder joint, with its extreme range of motion, demands.Teres Minor: This works with the infraspinatus muscle to also perform external rotation of the shoulder joint.Infraspinatus: This is a muscle on the back side of your shoulder that performs external rotation of the shoulder joint.It works in tandem with your deltoid muscle to stabilize the shoulder joint as you lift your arm! Supraspinatus: This is often the culprit of rotator cuff injuries, as it takes on the most load in comparison to the other rotator cuff muscles.If these muscles are not working with one another the right way, that is when we may have issues of pain and/or potential injury. There are four rotator cuff muscles. As previously mentioned these muscles work in unison with one another to create a compression mechanism at the shoulder joint, allowing for optimal stability as you move your shoulder in different planes of movement. Normally, this 10mm of subacromial space is maintained as we move our shoulder throughout its range of motion through the stabilizing actions of a strong and intact rotator cuff. The area between the humeral head and the coracoacromial arch of the scapula is known as the subacromial space.This space is extremely tiny, between 9-10mm! In this small space lie some very important structures, including the supraspinatus tendon, biceps long head tendon, subacromial bursa, and superior labrum. The downward shear force is vital in preventing the head of the humerus from migrating upwards. ![]() The compressive force is vital to keep the head of the humerus centered within the glenoid fossa. The rotator cuff primarily exerts a compressive and downward shear force at the glenohumeral joint. The rotator cuff is a group of four muscles that is intimately associated with our main shoulder joint. What Is The Rotator Cuff? Why Is It So Important?
